The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.

To shown in Figure 5, the LED lamp comprises housing 1 and end cap 2 as Fig. 1.Housing 1 has a storage tank 101, be formed with step surface 102 on two madial walls of housing 1, described step surface 102 extends along the length direction of housing 1, be positioned on the madial wall of housing 1 step surface above be provided with slot 103, slot 103 is two, and is parallel to each other.Be provided with radiating fin 104 on the outer wall of housing 1, to improve radiating efficiency.Length direction along housing in housing is formed with cavity body 105, like this, can not only increasing heat radiation area, improve radiating effect, and can save material, also can not affect the outward appearance of LED lamp.Described end cap 2 is arranged on the two ends of housing by screw, the top edge of end cap 1 is lower than slot 103.

Substrate 3 is installed on the inner bottom surface of housing 1, LED4 more than two is installed on substrate 3, and all LED4 are arranged in a row, on each LED4 to reflector 5 should be arranged, reflector 5 top edges have flange 51, flange 51 is fixed on step surface 102 by screw, and realization is fixing to reflector, is provided with eyeglass 6 on the top edge of reflector, eyeglass 6 is fixing by pressing plate 7, pressing plate 7 is fixed to by screw on the flange of reflector, and as shown in Figure 2, the position that reflector is corresponding has light hole 71.This structure, with respect to prior art, fixing more firm, the reflector of reflector are not easy to be subjected to displacement, and therefore, the light extraction efficiency of LED lamp is high, and optical quality is good.

To shown in Figure 4, be inserted with optical accessories 8 as Fig. 2 on slot 103, optical accessories can be color chips, also can be the lamp cylinder, also can be LGP etc.
