Abstract

The utility model provides a brand-new LED (light-emitting diode) panel light with a lamp panel on which lamp beads are arranged. Lamp beads of two different color temperatures are mixed and arranged on the same lamp panel in sequence at intervals, 1,3,5 and 7 shown on the picture are warm white lamp beads and 2,4,6 and 8 are cold white lamp beads, the warm white lamp beads and the cold white lamp beads are mixed and stuck on an aluminum substrate 9 in sequence at intervals, therefore, luminous sources of the two different color temperatures are mixed and arranged by a luminous unit as small as possible and the distance as short as possible, and a color temperature light effect is good by adopting the lamp panel with the mixed lamp beads as the luminous source of the panel light. The panel light has even mixed light, the same color temperature has even light and has a good luminescent effect, and the same panel light has no light spots of other color temperature; in addition, one lamp panel is provided with the lamp beads of two color temperatures, the panel light has low incident light requirement and does not always require incident lights from all sides, so that the requirements on quantity of lamp panels and shells are lowered, the LED panel light can be diversified, for example, the shape of the panel light can be rectangle, roundness and polygon but not always the square, therefore, the products are flexible and are diversified, the cost of the products is lowered and the economic efficiency is obvious.

Description

LED lamp pearl mixing formula color-temperature regulating flat lamp

Technical field: the utility model relates to LED color-temperature regulating flat lamp.

Technical background:

LED color-temperature regulating flat lamp is to select to warm up in vain, the LED lamp pearl of cold white two kinds of different-colours is cooked light source, two kinds of light sources inject LGP simultaneously, reflect through the LGP mixed light, provide illumination through after diffuser plate again, this flat lamp with two kinds of color temperature lamp pearls coordinates the LED controller with two groups of outputs, one group of output is controlled and is driven warm white lamp pearl, another organizes output, control and drive cold white light pearl, by changing respectively the size of the output current of two groups, go to change the luminous intensity of warm white and cold white light pearl, due to warm white, the luminous intensity variations of cold white light, the colour temperature effect of the light that sends after two kinds of lamp pearls are mixed has just changed.Color-temperature regulating flat lamp in the past, structure chart such as Fig. 1: take four lamp plates (the lamp pearl is attached on the single-sided aluminum-base plate), four sides to advance the light mode, minute two warm white lamp plates and two cold white light lamp plates only have a kind of lamp pearl on a lamp plate.Relative lamp plate is the lamp pearl of same colour temperature, and 1a and 3a are warm white lamp pearl, and 1b and 3b are warm white lamp plate, and 2a and 4a are cold white light pearl, and 2b and 4b are cold white lamp plate, and 5 is diffuser plate, and 6 is LGP, and LGP is interior, and diffuser plate outside.

Owing to being a kind of lamp pearl of colour temperature on a lamp plate, the light of two kinds of colour temperatures is difficult to mix, place from lamp plate close to more, the just more difficult mixing of warm white or cold white light, hot spot with the mixed light different-colour of centre can appear in the surrounding of flat lamp, and this mode also necessarily requires the four sides to advance light, and it is four foursquare that flat lamp requires, otherwise light mixing effect is more undesirable.

Summary of the invention:

Design a kind of brand-new lamp plate of lamp pearl alternate mixing arrangement mode on the same lamp plate of two kinds of different-colours for the problems referred to above the utility model, like this, the light emitting source of two kinds of different-colours is with as far as possible little luminescence unit and distance, mix arranged together, adopt this lamp plate to make the light emitting source of flat lamp, make mixed colour temperature light efficiency better.

the beneficial effects of the utility model are on flat lamp, any one even light mixing, same colour temperature is luminous evenly, illumination effect is good, on the one flat plate lamp again without the hot spot of different-colour, in addition, article one, has the lamp pearl of two kinds of colour temperatures on lamp plate, the requirement that flat lamp is advanced the light mode reduces, not necessarily require the four sides to advance light, reduced the requirement to lamp plate quantity, requirement to shell, also can allow the variation of color-temperature regulating flat lamp, such as rectangle, circular, irregular polygonal can, it is square de-emphasizing, like this, both increased the flexibility of product, enriched the variation of product, also reduced the cost of product, economic benefit is obvious.
