[Prior Art] Light Emitting Diode (LED) or High Light Emitting Diode (HLED) has the characteristics of small current and low power. Widely used in a variety of commercially available electronic products. Although the power consumption of a single light-emitting diode is extremely low, the heat generated by the light-emitting process will gradually accumulate and cause a thermal effect, which affects its luminous efficiency and service life. When increasing the illumination brightness, most of the light-emitting two are used simultaneously. In the case of polar bodies, the effects of thermal effects are exacerbated. Because of &, the light source of the LED has a very high requirement for heat dissipation. The relatively high heat dissipation requirement has also limited the application and development of the light-emitting diode lamp. Referring to Figures 1 and 2, the LED illumination device of the inventor's application No. 94138111 provides an illumination device which can improve illumination brightness, increase heat dissipation and reduce thermal effects. »Hai LED lighting device! a light-emitting unit 12 having a heat-dissipating unit, a light-emitting diode 12 attached to the heat-dissipating unit 11, a projection cover 13 disposed around the light-emitting diode 12, and a power supply unit 14 electrically connected to the light-emitting diode 12 The heat dissipating unit 11, the light emitting diode 丨2, the projection cover 13 and the power supply unit 14 are housed in the outer casing unit u. The heat dissipating unit 11 is of an aluminum extrusion type and has two parallel sides 1307749 111, A bottom wall 112 connecting the two side walls 111, and a protruding portion 113 formed on the bottom wall 112. The bottom wall 112 is adjacent to the two side walls 1U and recessed to form two latching grooves 114. The diode 12 is adhered to the protruding portion 113 of the heat dissipating unit 11 by a thermal conductive adhesive 1 . The projection cover 13 has a peripheral wall 131 surrounding the light emitting diode 12 , and two extend from the peripheral wall 131 . The power supply unit 14 has a control circuit 141 disposed on a circuit board 14 , and is electrically connected to the control circuit 141 . The rechargeable battery 142, a power switch 143, a power indicator 144, and a power outlet 145 are utilized The power socket 145 can be connected to the external power to charge the rechargeable battery ι42, and then the power switch 143 can be switched, so that the power of the rechargeable battery 142 can be supplied to the light-emitting diode 12 for use as a flashlight or general indoor lighting. The control circuit 141 is designed to have the function of power-off activation, and the illumination device can be further applied to the emergency illumination of the power failure. Although the LED illumination device can be cooled by the connection with the LED 12 The single TG 11 increases the heat dissipation effect' and utilizes the projection structure of the projection cover 13 and the heat dissipation unit 11 to achieve a simple assembly function, but the following points can be further improved: since the light-emitting diode 12 is The thermal adhesive 1〇 is adhered to the diffuser..., unit 11. Although it has reached the end of its useful life or has failed, it cannot be removed directly. It may have to be replaced in the whole group, or scrape the thermal conductive adhesive 0 first, and then the new 1307749 The light-emitting diode u is adhered to the heat-dissipating unit u by the heat-conductive adhesive 10, which is relatively inconvenient for maintenance and assembly. Second, although the control circuit 141 $ can be automatically powered off. Ming functions, but if the power outage in the middle of the night people sleeping time, there may not be a timely reminder of the lack of warning Qi, relatively when used on emergency lighting, security incomplete and inadequate compared to the disadvantages.

The two circuit strips of the protruding port 223 are electrically connected to obtain power supply, and the light emitting diodes of the lamp unit 3 are connected in parallel and arranged side by side. The failure of the body 31 affects the function of the normal light unit 3, and the user can flexibly adjust the number of the light unit units 3 to be installed according to the space and the demand for illumination brightness, so that the lighting device can be adapted. The use of convenient and flexible adjustment, and a wide range of applications. The following is an explanation of the effect of setting the heat dissipating unit 2 and the projection cover 32 on the result of an experimental test, which is the result of testing with the lamp a, and the result of testing with the lamp B is shown in Table 2, and the experimental tests of both are When the ambient temperature is 21 ° C and the illumination test distance is 5 〇 cm, different currents of the array are supplied to the lamp A and the lamp B respectively, and the lamp A is measured at different time points after continuous power supply. Lumen and temperature values with the luminaire B. The lamp A is a design in which the light-emitting diode 31 is placed on an aluminum substrate (not shown) on which a printed circuit is disposed, and the projection cover 32 is not covered on the light-emitting diode 31. In the lamp B, the light-emitting diode 31 is directly disposed on the heat-dissipating unit 2, and the design of the projection cover 32 is covered on the light-emitting diode 31.
